我厂上φ350×2/φ270×4二列式型材车间已于1986年投入生产。在设计中采用了斜辊式冷床,目前国内使用尚少。经过调研分析与改进,达到了良好的使用效果。 该车间年产量为8万吨,产品规格为φ16～25普碳圆钢、φ16～25低合金螺纹钢,其产量占70％。其它品种有(8～12)×(30～65)普碳扁钢、36～45号角钢等。要求成品冷却到300℃以下,达到国家允许的弯曲度。 1.斜辊式冷床的选用 目前的型钢冷床型式有推齿步进式、斜辊式、多爪式、小车多爪式、小车潜行式与摇摆式等。适合我厂生产要求的有推齿步进 I plant φ350 × 2 / φ270 × 4 two-story profile workshop was put into production in 1986. In the design used inclined roller cooling bed, the current domestic use is still small. After investigation and analysis and improvement, reached a good effect. The workshop annual output of 80,000 tons, product specifications for the φ16 ~ 25 Cape carbon steel, φ16 ~ 25 low alloy rebar, the output accounted for 70%. Other varieties are (8 ~ 12) × (30 ~ 65) Cape carbon flat steel, 36 ~ 45 angle steel. Requirements of finished products cooled to below 300 ℃, to allow the country to bend. 1. Slant roll cooling bed selection The current type of steel cooling bed push the teeth step, inclined roller, multi-claw, car multi-claw, sled and swing car and so on. Suitable for the production requirements of our factory have pushing teeth step
